Boot path
Stage 1 loads Stage 2. Stage 2 handles disk reads, memory information, graphics handoff, protected mode, and the contract passed into the kernel.
Technology
The part users do not see is the reason it matters.
Sky OS is built around its own boot path, protected-mode kernel, filesystem, GUI path, process foundations, and hardware detection work.
Kernel
The current line focuses on a 32-bit protected-mode kernel with IDT, PIC, PIT, keyboard, mouse stubs, memory work, shell, and diagnostics.
SkyFS
SkyFS V2 is being shaped for typed files, multi-sector data, path-style directories, allocation bitmap, and recovery journal operations.
GraphicsVBE framebuffer handoff when available, VGA fallback when not, plus SkyGUI v2 drawing paths.
ProcessesSKYEX runner, PIDs, process list, cooperative scheduling records, wait/exit ideas, and handle mapping groundwork.
HardwareCPUID, ACPI table parsing, PCI scan, APIC/IOAPIC planning, and target registry for x86, x64, ARM64, RISC-V, and display backends.
NetworkingInternal Ethernet/ARP/IPv4/UDP model exists, but real external networking still needs a NIC backend.
